Mid-Field Configuration – This configuration is basically the same as the Close-Field set-up. (see Figure 2) It is normally used with larger monitors or when the monitors are too large or heavy for the meter bridge. This set-up has the potential for a larger sweet spot and better spatial imaging. Make sure that the height of the woofer is above height of the console.

SUBWOOFER SET-UP
Begin by determining the best location for your subwoofer. If possible, the optimum set-up would look like the set-up in Figure 3. This set-up may not be practical or possible in your room. Once you have set up your monitors. Listen to some program material that you know has low frequency information recorded on it. Different locations may create a phase misalignment. Most Subwoofers have a phase switch on them. Flip the phase switch. The bass response volume will either increase or decrease in volume. Whichever setting gives you the loudest response from your seating position is in phase. After you have the proper phase setting you will need to adjust the output level of the Subwoofer to a level that provides a smooth blend of the bass volume with that of your monitors.
